Some points to help clarify the situation: 1. There is no other way to archive a dataset than using a snapshot 2. You cannot build a zpool on a tape 3. The stability of the protocol is only a problem if it becomes impossible to run some version of OpenSolaris on hardware that is needed to receive the snapshot. Given the ubiquity of virtualization and the x86 legacy, I don't think this is a problem for at least the expected lifetime of the storage medium. > A lot of people are now going to use that to archive their data, and > some of them are not going to be happy when months or years down the > line they try to restore it and find that the 'zfs receive' just > fails, with no hope of recovering their data. > > And they're not going to blame the device that's corrupted a bit, > they're going to come here blaming Sun and ZFS.

Data integrity is a problem for all archiving systems, not just ZFS. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
